Fig. 19 is a vertical sectional view taken through the pump piston.

Referring to the drawings, the apparatus illustrated as an example issupported by a base 25. The packaging head and its asso-' oiated partsare carried by a housing or frame 26 mounted on a cylindrical post 27tele-' scoping in a column 28 which forms part of the base. In orderthat the apparatus may be available for bottles of different standard 34to which power may be appiiediin any suitable manner.

In the embodiment illustrated, bottles are fed one by one to a syrupingdevice and the packaging head by a rotating dial or spider having a stepby step movement. Although capable of Y various constructions, as hereshown, carried by the base is a bottle supporting table 35.Rotating-above this table is .a bottle feeding spider 36 having aplurality of spaced bottle-centering pockets 37. This spider is drivenby a shaft 38 to which is pinned a collar 38. Clamped to the collar is asleeve 38 having a squared head on which the spider 36 is mounted bymeans of a squared socket 36*. The shaft 38 is journalled in table 35,and carries a ratchet 39 provided with spaced notches 401 JIhis ratchetis engaged by a spring-pressed pawl 41 mounted on a pawl carrier 42which is supported by an arm 43 hung from shaft 38. To reciprocate thepawl carrier. securedthereto is a connecting rod 44 slid-ably connectedwith a sleeve 45 between which-and the end of the rod 44 is a spring 46.The sleeve 45 is secured to one end of anoperating lever 47 whichcarries a roller 48 running on a bottlefee'd cam 49 on shaft 31. Aspring 50 holds the roller to the cam.

Under normal conditions, the operation of the lever 47 by the camactuates rod 44, through the spring 46, to drive the pawl car ricrsShould there be a jam, however, or like opposition to the movement ofthe pawl and ratchet, the lever 47 and sleeve can Yoperate againstspring 46 without moving lar pawl 52 locks the ratchet against forwardmovement following each feeding movement. The two locking pawls are heldto their duty by a spring 53 connecting them. The awl 52 is dislodged topermit 'the next orward stroke by awiping arm 54 on arm 43 which engagesthe pawl on the backward stroke of pawl carrier 42.

Bottles placed in'the pockets of the feed ing spider 36, are fed firstto a position beneath the syrupin device and on the next stroke to aposition beneath the paekaglng head. WVhilethe syruping device mayvarywidely in construction, instructurcs e1nbodying the invention to thebest advantage, 1t 1n-. cludes a ported receptacle, a bottle-controlledvalve for the port, and means for causing relative movement betweenreceptacle and bottle. The relative movement may advan-- tageously beobtained by a constructlon permitting the receptacle to descend to thebottle by gravity, the bottle being supported on table 35.. Althoughcapableot various consyrup may-fiow by gravity. The port57' isstructions, as here illustrated as an exam le, there is provided a syrupreceptacle 55 s idable in a bracket 56. In the lower art ofthereceptacle is an inlet'port 57 witl connected a flexible hose 58leading tea-suitable source of syrup supply from whlch the connectedwith the main part of the receptacle by a passage 59. In the rece tacleis a float 60, the upward movement 0 which is controlled by anadjustablepin 61. Syrup flowing into the receptacle raises the floatuntil it strikes the in 61, the syrup charge thus beingiadjustab vmeasured.

As before stated, the inlet and outlet ports are governed bybottle-controlled valves. To this end, as here illustrated, a nozzle 621s slidable in a sleeve 63 threaded into the bottom of receptacle 55,the top of the sleeve being bevelled to form a valve seat. Associatedwith passage 59'and opposite t-his valve seat is a second valve seat 64.The upper end of the nozzle 62 is formed with a double bevelled valvehead 65 capable of seating against one or the other of the two valveseats. Below this head 65 are a number of ports 66 formed in the wall ofthe nozzle 62 to communicate with the receptacle 55 when the nozzle israised. I

Fig, 5 illustrates the parts in syrup-receiving position. Nozzle 62 islowered, thus clos- 1 ing the exit port and opening the inlet port.

The nozzle is normally held in this position by a spring 67 between thesleeve 63 and a flaring guide mouth 62 on the nozzle 62. Then the nozzleis relatively raised the valve head moves up againstv valve seat64-tlIus closing the inlet port and shutting oil the s'tructions, ashere shown'as an example, the

receptacle is suspended by a flexible chain 362. This chain asses overguide pulleys 363, 364 and is anc ored as at .365. Mounted on a sleeve366 rotated as later described, is a crank arm .367 having achain-engagmg pulley or roller 368. The sleeve 366 also hasv a guidepulley 369. As the crank arm 367 rotates, whenithe 'pulley 368 isbrought against the chain, it will cause the chain to be hauled in withrespect to the receptacle, thus raisin the latter. As the pulley 368leaves the c ain, however, in the rotation of the crank arm, the chainis released to that extent and the receptacle is free to descend towardthe bottle by gravity. The parts are; I so arranged that the receptacledescends far enough to rest on the bottle so that the nozzle is forced uwardly. Adjustment of the receptacle stro e is automatically effected asa whole, as above described. It will be seen that the receptacle is inits lowered position long enough to permit the charge of syrup in thereceptacle to flow into the bottle. Continued rotation of the crank armagain starts to haul in the chain and as the receptacle leaves thebottle, spring 67 causes nozzle 62 to be lowered again, thus closing theexit valve and opening the inlet valve. Thus, during the pei'iod thereceptacle is held elevated, a new charge of syrup can enter from thesource of supply and the charged bottle is removed and an empty bottleadvanced. With the construction described the syrup reccptacle in itsmovement into bottle filling position accommodates itself to'bottles ofdifferent sizes. 7

-While one bottle is receiving syrup, the preceding bottle ispositionedbeneath the packaging head to receive its carbonated wateryandcap. There is provided means for causing relative movement betweenhottle support and packaging head and in structures embodying theinvention to the best advantage. the head is reciprocated to and fromthe bottle. Although capable of various constructions, in that hereillustrated as an exupon the adjustment of the head mechanism llt) ice

ample, the packaging-head includes a hollowv plunger 70 slidable inbearings 71 carried b the main frame. Threaded into the top of the pluner 70 is a nut 72 connected by a link 73 with a rocking lever 74fulcrumed on a shaft 75. Theother arm of lever 74 carries a roller 76running on a cam 77 driven by cam shaft 78. Pinned to the lever 74 as at375iis a second lever 374 having a roller 376 running on a cam 377 alsoon cam shaft 78. Through the mechanism described the tubular plunger 70is given the movements hereinafter more fully referred to. The cam shaft78 is driven by a gear 79 meshing with a gear 80 the hub of which issecured to abevel pinion 81. This pinion, which is rotated by a bevelgear 82 on shaft 31, is keyed to the sleeve 366 previously referred to,this sleeve rotating on a shaft 83.

In the exemplification here illustrated, the plunger carries a tubularhead member 84. This head member has an internal shoulder 85 and belowthis shoulder is located a throat carrier 86 with a conical throat ringor capping die 87. Formed in the throat is a crown chamber 386 belowplatform plate 486. Throat carrier and platform plate are supported aslater described. Extending into the capping die is a capping plunger 88tubular in form to accommodate described. The capping plungeris-relatively movable in the head and is normally held in its lowermostrelative position by" a spring 89. This spring, which is under someinitial compres sion, bears against a shoulder 90 on the capping plungerand against a shouldered guide sleeve 91.. The normal position-of thecapping plunger is -controlled by the engagement of its shoulder 90 withshoulder 85 of the head member, this engagement limiting the downwardmovement of the capping plunger. The guide sleeve 91 is threaded intothe head member 84 and the compression of the capping spring 89 isadjustable by rotation of guide sleeve 91.

The invention in its entirety includes a filling nozzle relativelymovable with respect to the head and having connection with a source ofsupply. In structures embodying the invention to the best advantage thenozzle is held during filling adjacent the lip of the bottle but out ofcontact therewith. The

invention in its entirety also includes valvemeans for cutting off thenozzle, controlled by the relative position of the nozzlewith respect tothe bottle. In a convenient embodiment of the invention the nozzledescends with the head to a given point and is then checked as the headcontinues downward a slight distance, tween head and nozzle opening thenozzle valve. Although capable of various constructions, in that hereshown as an exam le, slidable in the lower part of the cappmg channel 96and an which is a crown' this relative movement be-' plunger 88 is anozzle comprising a spiral internal bore 97. This nozzle is connected bymeans of a coupling 98 with a tube 99 which forms a continuation of bore97. The upper end of nozzle 95 is slidable in a shouldered collar 101which seats within capping plunger 88 above shouldcr 90 and is threadedinto a liquid supply tube 102. The top of the spiral channel 96 opensinto the interior of collar 101 to com-. municate with the supply tube.This supply tube is threaded into a coupling 103 into the side of whichis threaded an elbow coupling 104: having connection witha flexible hose105 later referred to.

In the present embodiment the coupling 98 has a bevelled head 98" whichseats against the bevelled rim of collar 101 and thus serves as a valveto out 01f the no'zzle. The unit comprising nozzle 95, coupling 98,valve 98 most relative position by a spring 106 which bears against thecoupling 98 and the cou pling 103. In this position (Fig. 6) the valveis closed.

Since valve 98' which is part of the nozzle unit, and since the valveseat is part of collar 101, which is on the supply tube, it will beapparent that the valve will be opened, i. e. separated from its seat,by a proper relative movement between the two units. In the presentembodiment this relative movement is effected by checking or snubbingthe nozzle unit just prior to the end of the downstroke of the supplytube. To this end, as here shown as an example, threaded to the top oftube 99-is an elbow coupling 107 for connection to the reservoir. laterreferred to. Connected to this elbow is a spring 110, its other endbeing connected to a chain108 which extends upwardly to the top of thehousing 26 where it is adjustably is part of coupling 98,-

anchored as at 109. In this way the nozzle 102 and coupling 103 descendswith it in the manner later set forth.

Through the spring 106 the nozzle unit also descends. This unitarymovement continues until the spring 110 has a given extension. arrangedthat this the end of the filling stroke of the head. WVhen this point isreached and during the completion of the filling the nozzle unit ischecked by its connection with the stationary frame. By this check ing,the valve element 98 the collar 101 with its valve seat continues Theparts are so downward, whereby thevalve and its seat are separated, thusestablishing communication between the nozzle and supply tube I 102.Also, the nozzle 95 is held just out of contact with the bottle lip. Inthis way there is no danger of breaking off the slight ridgeor web whichis often found on bottle lips. In constroke of the-head,

takes place just prior to is stopped while I structions where the bottleengages the nozzle this web is sometimes broken off and dropsconstructions, in that here shown as anexample, a compressible sealinggasket 111 of rubber or the like is seated in a gasket carrying cup 112below the platform plate 486 which serves as an abutment against whichthe gasket 'is compressed upon movement of the cup. On the cup 1.12 aretwo upright arms 114 having lugs 115 which are freely suspended innotches 116 formed in the upper ends of the arms 118 of the leverelement 117. To pivotally mount the lever device,

the latter has trunnions 119 journaled in the ends of suspension links121 which extend downwardly from the head and serve as a support. Theparts are so arrangedthat when the arms 118 are in a substantiallydead-center position the cup 112 is held up to compress the gasketagainst the abutment plate 486, and when moved out of such position thegasket is free-to re-expand. The

gasket assemblydescribed serves to retain the throat ring and crownplatform in position.

There is provided means dependent on the movement of the head foroperating the lever device 117. As here shown as an example, the leverdevice has a portion for receiving substitution and the like.

the lever device 117 is reversely tilted to swing the arms 118 out ofdead-center position. This permits the gasket to re-ex and so as toclear the attached cap as the ead moves upwardly again. It will be seenthat the ends of the slot of bar 124 provide, in effect, u per and lowerabutments for reversely actuating the lever device. In the presentembodiment the action of lever 117 may be timed by removing pin 123 andturning bar 124 on rod 424. I

The construction described provides, inaddition to an efiective gasketoperation that firmly holds'the gasket compressed, a convenlentdisassembly unit. In the operation of packaging apparatus it isdesirable to remove the seallng gasket after each days being subject towear, it is sometimes necessary to remove these parts for inspection,

With the construction described, throat, platform, gasket and "gasketcarrier form an assembly unit held in place by'the lever arms. ponremoval of pin 123, the lever 117 may be manually tilted to releaseposition, whereupon the assembly unit referred to drops out. To replacethe unit, the parts are returned to proper position, the lever 117actuated to snap the arms 118 into dead center position and the pm 123replaced.

Means is provided for supplying caps. such as crown corks to thepackaging head. In the present embodiment, a hopper of any su1tableconstruction for supplying crowns faced one way, shown generally at 301,is carried by the stationary housing 26. The

an actuating force, comprising a double arms. hop er shaft 302 is drivenby a bevel gear 303 WVhen the head makes its up stroke the enagementof-the pin 123 with the upper end of the slot of bar 124 causes thelever device 117 to tilt so that its arms 118 move intov a substantiallydead-center position. This movement raises the on 112 and compresses thegasket against the a utment plate. Thi position of the parts may betermed the normal position, the gasket being held compressed until thelever device is reversely actuated. As the head descends, the pin movesdown the slot of bar 124 and is, in effect, free but the gasket is heldcompressed due to the arrangement described without the exertion offorce on arm 122. As the to, pin 123 engagesthe bottomof its slot and inthe throat carrier 86-.

Means is provided for yieldingly holding the end of the chute in givenposition. Although capable of various constructions, as here shown as anexample, pivoted to a bracket 314 on the chute is a rod 315 extendinginto a casing 316. This casing is con nected to a pin 317 pivoted to oneof the guide brackets 71 on the main frame. A compen-' sating spring 318is located between a collar 319 on rod 315'and a nut 320 in the casing316. \Vith the construction described the delivery and of chute 310 isnormally held in a stationary position but it is yieldable in case of ajar? or the like, by compression of spring in register with chute 310, acrown enters the crown platform chamber and is held to one side by thenozzle (Fig. 6). As the head descends the plate 311 moves down past thechute mouth and blocks the same until the head is again raised.Adjustment of the chute position may be made by adjusting Means isprovided for sealing the crown entrance port duringthe packagingoperation and for moving the crown into position for capping. As hereshown as an example, a port closer 130 is pivoted to the head as at 131to swing to and away from the port 312. The closer is a cylindricalmember haviing an annularly grooved head in which is seated a sealinggasket 132. At its other end the closer 130 has a back plate133 and anassembly nut 134.

There is provided means dependent on the relative position of the headfor operating the port closer Although capable of various constructions,in the present embodiment the closer 130 has side extensions 135 towhich are pivoted upwardly extending angle levers 136 having slots 137.These'levers, at their upper ends are pivoted to a rod 138 extendinginto a casing 139 pivoted to the main frame as at 142. Between thebottom of the casing 139 and a collar 140 on the rod 138 is a spring 141which serves to hold the closer closed against the pressure of theliquid. To operate the levers 136, the slots 137 ride on pins 143carried by the head. As the head descends, therefore, the port closer130'is swung on its pivot to the position of Fig. 7 in which the gasketis pressed against a portion of plate 311 which may be grooved as shown.This movement causes a slight compression of spring 141' whereby thecloser is held closed against the pressure in the head. Upon upwardmovement of the head the pins 143 riding up the lever slots return thecloser to its former position.

The closer 130 also serves as a housing for the drown pusher. In thepresent em-.

bodiment, within the closer 130 is a bodily movable block 145 normallypressed forward by springs 146 which bear against the back plate 133.The block 145 is suitably chansli'dable in the block 145 vand normallyneled to receive a crown pusher 147"(Figs.

7 and 8) which has rack teeth meshing with a toothed segment 148 mountedon a pin 149 which is ournalled in the block 145. The pin 149 has asecond segmental gear 150 which meshes with rack teeth on an actuator151,

pressed forward by a spring 152.

Fig. 6 shows the arts in inactive position with the actuator s ight-lyin advance of the pusher. As the closer 130 is drawn into sealingposition the actuator'engages the plate 311 and the pusher engages thecrown which is held back by the nozzle as. before described. By thispressure, a large part of which is taken by the actuator, the block 145is pushed back against its spring, spring 152 also being com ressed.When the nozzle is raised, as

hereinafter described, the crown is released and the block 145 movesforward under the force of its springs, the pusher 147 pushing the crowninto capplng position. During this movement the actuator 151 is stillheld against the plate 311,-the two segmental gears rolling along thetwo racks. When, upon elevation of tlie head, the port closer is movedaway from the head, the actuator is released. Its spring 152 now pushesit forward to normal position, and this movement through the racks andsegmental gears pulls the pusher 147 back to normal position.

The closer housing 130 may serve as a grip portion for manual operationof the port closer. With the construction described the operatingconnection can yield under manual operation. As 'a result, the portcloser can be swung open manually while the machine parts are inport-closing. position, to give access to the crown port in case of acrown jam or the like.- This permits a jam to be relieved withoutrunning the machine through its cycle to .open the port closer in thenormal way. r

The bottle being sealed in the head and the crown entrance port closedand sealed, the charge of carbonated water is delivered to the ,bottle.The apparatus here illustrated as an example embodies the filling systemdisclosed and claimed in applicants earlier application Serial No.243,652 (Patent 1,556,837). As shown, gas from a source 160 and water(for example) from a source 161 are delivered to a carbonator 162 whichmay be of any suitable construction. A pipe 163 conducts the carbonatedliquid, carbonated at a higher pressure than'ultimately desired, to areducer valve 164. This reducer valve may be of any suitableconstruction but it is conveniently located on top of a tank 165 formingthe reservoir to which is delivered the carbonated liquid and freed. as.

There is provided a pressure line in which the bottle is connectedduring filling. This pressure line includes the reservoir formed by tank165 and which contains carbonated liquid and freed gas, a connection forthe passage of liquid from the tank to the bottle and a connection forthe passage of gas and air between the bottle and the upper part of thetank, In the liquid connection is a the construction here illustrated asan example, a pipe 166 leads from the bottom of the tank 16510 a passage167 in a valve casing 167, near one end thereof (Figs. 4 and 5). Spacedaround the valve casing in the same radial plane with passage 167 aretwo other passages 168 and 171. Passage 168 is connected by a pipe 169with the bottom of a pump cylinder 170 and passage 171 is connected by apipe 172 with the hOse 105 which conducts the liquid to the supply tube102 and the spiral channel of the nozzle. It will now be apparent that,through the valve casing, .the reservoir may be connectedwith the pumpcylinder and the pump cylinder with the nozzle. To control the flowthrough the valve casing, as hereshow'n as an example, rotatable in thevalve chamber is a plug valve 173 acting as a three-way valve for theliquid. This valve has a partial circumferential groove 174 in the planeof the three passages described. Theparts are so arranged that groove174 can span passages 167 and 168 or passages 168 and 171 but notpassages 167 and 171. Fig. 4 shows the valve with its groove174.spanning passages 167 and 168, thereby connecting the reservoir withthe pump cylinder. Upon proper rotary movement of the valve, its groovewill span passages 168 and 171, thereby connecting the pump cylinderwith the nozzle. As the valve rotates, therefore, it alternately permitsa flow from reservoir to pump and a flow from pump to nozzle.

While the gas and air connection between the sealed bottle and thereservoir may be effected in various ways and at vanous periods in thefilling cycle, in the embodiment here illustrated this connection iscontrolled by valve 173.and the connection is opened just prior to theflow of'liquid in order to set up counter-pressure in the bottle. Tothis end, valve casing 17 3 has, near its other end, two passages sage175 is connected by a pipe 176 with the reservoir 165 at a point abovethe water level. Passage 177 is connected by a pipe 178 with thecoupling 107 which communicates with tube 99 and the inner bore 97 ofthe nozzle. Valve 173 has a second connecting groove 179 arranged tospan passages 175 and 177 during a portion of the cycle of valverotation. \Vhen the valve is in this position, therefore, the bottle isin communicating connection with the reservoir and is made part of the)ressure line. In the particular embodiment illustrated as an example,the parts are so arranged that this connection will be opened just priorto the flow of liquid so that counterpressure will be set up in thebottle prior to the liquid flow.

To rotate valve 17 3, as here shown as an example, secured to the innerend of the valve, which is conical to fit the conical chamber of thevalve casing and is pressed in.- wardly by a spring 180,, is a crank arm181 175, 177 (Fig. 15). Pas-.

cam 183 passes on and cam 184 actuatesflfi the valve to move it to closeposition, cutting off communication between the bottle and reservoir andcutting off the nozzle from the pump. In this closed position of thevalve the connection between the pump and reservoir is opened so thatthe pump may receive a new charge.

'In the system of filling referred to, the liquid is pumped against thecounter pressure in the bottle by a pump having a given stroke, in orderto deliver measured charges, and this stroke is adjustable. In theembodiment here illustrated, the pump includes the cylinder 170 and apiston 187 which has a iston rod 188 secured to the bottom of a slottedbeam 189. A slide rod 190 is secured to the top of the slotted beam andreciprocates in a guide bracket 191. Riding in the slot 192 of the beam189 is a crank block 193 carried by a crank 194 which is keyed to theend of shaft 78. The crank 194 is grooved and the block 193 which ismounted on a threaded rod 195 is slidable along this groove. As thecrank 194 rotates, the crank block, sliding in slot 192, reciprocatesthe pump piston with a given stroke. To adjust this stroke, the partsare moved to the position of Fig. 17 with the slot 192 and the groove ofthe crank member parallel, whereupon the crank block can bemoved alongthe groove by turning threaded pin 195. As will be apparent, this changein the position of the and the upper part of the reservoir, throughthebore 97 of the nozzle, tube 99, coupling 107, pipe 178, valve groove179 and pipe 176. This places the bottle in the pressure line wherebythe gaseous content of the reservoir sets up counter-pressure in thebottle substantially equal to the water pressure. This movement of .thevalve also, and slightly later, connects the pump with the supply tube.The pump piston now makes its forcing stroke and the measured liquidcharge in the pump cylinder below the piston is impelled into the bottleviapipe 169, valve groove 174, pipe 172, hose 105, supply tube 102 andthe spiral channel 96 of the nozzle. During filling the air and gasdisplaced from the bottle by the inflowing liquid flows upwardly throughnozzle bore 97, tube 99, pipe 178, valve groove 179 and pipe 176 to thereservoir.

l/Vith the construction described the liquid flows into the bottle andthe bottle is evacuated against a substantial pressure so that there issubstantially no loss of gas from solution.

After the pump has completed its forcing stroke, which delivers adefinite measured charge to the bottle, valve 173 is moved to closedposition cutting off the connection between the nozzle and the pump andthe connection between the bottle and the reservoir but openingcommunication between the reservoir and pump. As the pump piston makesits reverse or suction stroke, a new charge is drawn from the reservoirto the pump cylinder via pipe 166, valve groove 174 and pipe 169. Asliquid is withdrawn from the reservoir, more liquid and free gas flow infrom the reducer valve until a balance of pressure with the entrappedair and gas is set up.

Means is provided for venting the gas and air when a given amount hasaccumulated; To this end, as here shown, in the reservo r is a float 198controlling a valve 199 in a passage leading to a vent 200. VVhen theair and gas content of the-reservoir cause the lap uid content to dropbelow a given point, the float drops sufliciently to open valve 199.This allows the'air and gas content to escape until the resulting inflowof water raises the float and again closes the vent valve.

To balance pressures in the pump the top of the pump cylinder is incommunication with the reservoir through a pipe 201.

Means is provided for preventing an excessive escape of gas in case abottle bursts during filling and in structures embodying the inventionto'the best-advantage this is accomplished by cutting off the air-gasconnection to the bottle. As here shown, as an ex ample, in the pressure202 which connects the reservoir with gas and air pipe 176 is a valve203 normally open and controlled by a float 204. In case a bottlebursts, the pressure line is opened to the atmosphere and the suddenflow of gas and air from the reservoir permits an abnormal inflow ofliquid. This causes the water level to rise to such an extent as toraise the float 204 and close valve 203. This shuts off the flow of gasfrom the reservoir until the liquid level has again dropped sufficientlyto lower float 204 to normal position with valve 203 open.

There is provided relief means for the pump. As here shown as anexample, pump piston 187 has a passage 207 therethrough normally closedby a spring-pressed ball valve 208. In case the machine should beinadvertently-operated with the pump adjustment set fora bottle largerthan the bottle actually presented, any excess pressure the pump mighttend toset up in the bottle or line is relieved by valve 208 openingagainst its spring.

It sometimes happens that a bottle is not presented to the packaginghead by the feed ing mechanism, and means is provided for preventingoperation of the head and plug valve when no bottle is present. In thepres ent embodiment a clutch 205 is provided. This clutch, which is ofthe type described in the co-pencling application above referred tocontrols the operation of the various cams, and is operated by a wiper206 in the path of the bottles. i

After the bottle is filled it is capped while still sealed in the head.Means is provided for raising the nozzle so that the waiting crown canbe moved into position and the capping plunger operate. In theembodiment here illustrated as an example, the coupling 103 which isthreaded to supply tube 102, is connected by a link 215 with a rockerarm 210 fulcrumed on shaft 75. The other end of this rocker arm 216carries a roller 217 actuated by a cam 218 on cam shaft 78. Cam 218 isarranged to cause link 215 to be raised following the filling operation.Raising of link 215 raises supply tube 102 and its collar 101. Duringthe first portion of this movement collar 101 moves into engagement withthe valve head 98 of coupling 98, thus shutting off any flow to thenozzle. Thereafter. continuedupward movement of collar 101 bearingagainst coupling 98 raises the nozzle unit. The nozzle being thuswithdrawn from the crown chamber 380, the waiting crown is moved intocapping position as above described.

A spring 219 connected between rockerarm 216and the main frame isextended by this upward movement of the supply tube 102.

This spring later causes the supply tube to descend'with the head, asabove referred to.

Meanwhile, rotation of cam 77 through rocker lever 74 gives thepackaging head a further downward movement for the capping operation.During this movement the comressed gasket 111 slips down the neck of theottle, and the waiting cap is picked up by the bottle mouth and pressedagainst the capping plunger 88. As the capping stroke continues thecapping plunger 88 is forced back against spring 89 and through thepressures set up and the throat ring 87 a seal is made and the skirt ofthe cap is crimped on the bottle in the manner Well known in the art.During the latter part of the capping stroke of the head the gasketcompressing mechanism is actuated to release the gasket. The gasketthereupon expands or opens so that it can clear the cap on the upstrokeof the head.

Since bottles of a standard size vary someits syrup,

what in height, compensating mechanism is provided. Although capable ofvarious con- 4 yields slightly against spring 235.

There is provided means for braking the return movement aftercompensation. This may be accomplished, for example, by a dash pot. Ashere shown, the rod 232 extends into an oil reservoir 2% and has on itsend a pisston 237. This piston has a port 238 anda second port 239closed on upward movement of the piston by a ball valve 240. Thereservoir has a vent plug 241 near its top, a filling tube 24-2 and avalve plug 213. The reservoir 236 being filled with oil or the like,when the piston is forced down by the compensating movement, the oil canpass upwardly by the two ports 238, 239. But upon return movement whenpressure on spring 235 is removed, port 239 is closed and the movementof the piston is slowed down. This dash pot construction prevents theshocks and jars of a too sudden return movement.

lVhile it is thought that the operation of the apparatus will be clearfrom the foregoing description, it may be briefly reviewed as follows:Eaclrstroke of the bottle feeding mechanism positions an empty bottlebeneath the syruping device; positions the preceding syruped bottlebeneath the packaging head; and removes the filled and capped bottlefrom packaging position. During the pause between feeding movementsof'the bottle spider, the syrup receptacle descends and under itscontact with the empty bottle its nozzle 62 is raised, thus opening thedelivery ports 66 and closing the inletport 57, the measured charge ofsyrup flowing into the bottle. \Vhile the empty bottle is receiving thepreceding bottle is receiving its charge of carbonated water. As the camshaft 7 8 rotates, the earns 77 and 377 permit the head to descend firstto filling position. In the raised, or normal, position of the head thenozzle 95 extends through the crown chamber 386. as shown in Fig. 6, andthe gasket is held restricted as described. During the greater part ofthe filling stroke of the head all the associated parts descendtogether. The tubular plunger 70, the head member 84- and the guidesleeve 91 are connected together as a unit; capping plunger 88 followsthis unit because of its spring 89 supply tube 102 also descends becauseof the spring 219; and the nozzle unit comprising nozzle 95, coupling 98and air and gas tube 99 descend with the supply tube because of spring106. During this unitary movement of the head the valve 98 is closed.Meanwhilethe crown received when the head was raised is held back by thenozzle, the crown entrance port 312 has'lett the chute mouth which isblocked by the bearing plate 311, and the port closer is being swunginto closing position as described. As the head reaches the bottle, thebottle mouth is re ceived and sealed by the compressed gasket, asappears in Fig. 7. Just prior to this the distention of spring 110"checks the move ment of the nozzle unit, thus holding the nozzle out ofcontact with the bottle and separating valve 98 from its seat, asappears in Fig. 7. The filling operation now takes place in the manneralready described in detail.

\Vhen the filling pump has completed its stroke, the nozzle iswithdrawn. This is done by the elevation of the supply tube 102 by therotation of cam 218, this upward movement of tube 102 first bringing thecollar 101 against the valve coupling 98 to shut off the liquid flow andthen, by its continued en gagement with coupling 98, raising the nozzle.The withdrawal of the nozzle permits the waiting crown to be moved intoplace by the pusher finger 147 as described.

The head is now given a further downward movement for the capping strokeby the cam 77. As the head descends the cap is picked up by the bottlemouth and pressed against the capping plunger 88 which is forced backagainst its spring 89. The pressure thus set up effects a seal betweencap and bottle and the action of the capping die 87 crimps the skirt ofthe cap on the bottle in the manner well known in the art.

Meanwhile the rotation of the plug valve has closed the liquidconnection from pump to nozzle, and the air and as connection from thereservoir to the nozzle, thus cutting the head out of the pressure line.Also, during the latter part of the capping stroke of the head thegasket has been released in the manner described.

Packaging head and syruper are now raised. As the crank arm 367 rotates,it again engages the'chain 362 and the syrup receptacle is lifted awayfromI the bottle. As this movement takes place the syrup nozzle 62 isfree to close under the force of its spring and this movement closes thedelivery ports 66 and opens the inlet port 57 to admita new charge ofsyrup. As the same time rotation of cam 37 7 raises the packaging head,through lever 374 back to normal position, the capping plunger, supplytube and nozzle unit taking their normal relative positions as the headis raised. During this return stroke of the head the port closer isswung down to inlit active position, and the engagement of pin 123 withthe top of slot 124 again constricts the gasket as described.

It will be apparent that many of the 0peral ions here described assuccessive are more or less simultaneous, and it is to be understoodthat while the apparatus has been described as a soda machine and inconnection with c1'o\\'l1.(:01'ks and bottles, the invention is notlimited to any particular cap or receptacle. or to use with anyparticular liquid or liquids.
